Direct2Drive hosting huge 2K Games half off sale

Digital distribution retailer Direct2Drive is playing host to a pretty sweet deal for those who've been hesitant to pick up 2K's PC gaming offerings for reasons financial. D2D is offering a huge selection of their 2K Games catalog for half off until May 31. For just $9.95, you can nab Bioshock, Civilization IV, Serious Sam Gold, Prey and a few others -- or, for just $7.50, you can pick up the entire five-game X-Com series. That's $1.50 per game. If that doesn't blow your mind, you should really consider getting your frugality receptors examined.
